Application filed September 4, 1908.

To all whom it may concern:

Be it known that I, Jnssn G. VINCENT, a citizen of the United States,residing at Detroit, in the county of lVayne and State of Michigan, haveinvented certain new and useful Improvements in Adding and ListingMachines, of which the following is a specification.

In machines of this character it is common to employ a series of sprin-actuated hammers to do the printing and to provide for automaticallytripping o'lf hammers from left to right for the purpose of print ingciphers in decimal places of any amount where no digits occur. It isalso common practice to interrupt the tripping off of hammers when themachine is to be used for simultaneously printing two or more separatecolumns. Reference may be had to the Gooch Patent No. 825,205, July 3,1906, which shows an adding and listing machine of the well-knownBurroughs type (see Burroughs Patents ,Nos. 504,963 and 505,078,September 12, 1893) modified to provide for interrupting the automatictripping of hammers at will. Such a. machine is commonly termed splitand normal because of its capablity for operating either with all of thehammers related for the automatic tripping from left to right oroperating in the so-called split or divided state so that ciphers willnot be printed between items or amounts of separate columns.

The Gooch invention provides for locating the point of split variouslybut not for changing the location at will by the user of the machinethrough manipulation of devices on the exterior of the machine, thoughthis latter expedient has heretofore been practised in what is known asa variable split and normal machine.

The present invention relates to this last mentioned advanced type ofadding and listing machine and the principml object is N to secureincreased reliability in operation and convenience in manipulation ofthe special parts. The invention not only relates to the sO-calledvariable split and capabilities for restoring the machine to normal, butalso embraces regulating devices whereby the printing of totals for oneor more lists can be eliminated at will, as, for example, when lists ofdates or designating numbers or both are printed in association withlists of amounts. In this latter connection the Specification of LettersPatent.

Serial No. 451,667.

object is to positively lock varying numbers of impression devices suchas the hammers already'mentioned, whereby such elements are preventedfrom moving in a totaling operation.

In the drawings which accompany and form a part of this specificationFigure 1 represents a sectional left side elevation of an adding andlisting machine of the Burroughs type having the improvements of thepresent invention incorporated therein; Fig. 2 is a front elevation of acertain shaft for effecting the variable split; Figs. 3, 4, 5, 6 and 7are cross-sections of said shaft taken on lines 33, 4-4, 5-5, 66 and 77respectively; Fig. 8 is a front elevation of the hammer blocking shaft;Fig. 9 is a cross-section of the same taken on the line 99 of Fig. 8;Fig. 10 is a sectional right side elevation of part of the machine on anenlarged scale as compared with Fig. 1; Fig. 11 is a detail sectionalelevation of parts appearing in Fig. 10 but with the relative positionschanged; Fig. 12 is a sectional front elevation taken substantially onthe line 1212 of Fig. 1; Fig. 13 is a se tional top plan view takensubstantially on the line 1313 of Fig. 12; Fig. 14c is a detailsectional top plan view on the line 1 l14: of Fig. 10; Fig. 15 is asimilar view illustrating a changed relation of parts; Fig. 16 is afragmentary sectional right side elevation illustrating a constructionsomewhat different from that shown in Fig. 10 for controlling the hammerblocking devices; Fig. 17 is a fragmentary top plan view of the keyboardshowing indexing means employed with the construction shown in Fig. 16;and Figs. 18 to 23 illustrate samplesof different kinds of work themachine is capable of performing.

In the drawings the reference numeral 291 designates the usual amountkeys arranged in parallel rows with the keys in each row inscribed withnumerals from 1 1 The reference numeral 610 designates segmental racksof the usual form normally upheld by latches 415, the latter adapted tobe individually released by the depression of amount keys.

he reference numeral 611 designates the usual levers loosely mountedupon the rock shaft 600 and having slot and pin connections at theirforward ends with the racks 610, the rear ends of said levers carryingsegmental series of type plates (518 in front of a roller platen 17 in alaterally shifting carriage 17 at the back of the machine. Addingpinions 916 co'zE-perate as usual witl the racks (310, said pinionsbeing mounted in a rocking frame 910 having studs 958 and 958 above andbelow its center of oscillation.

The .reference numeral designates the usual total key surmounting theupstanding arm of a bell crank lever 227 which operates a universal bail216 for simultaneously displacing all of the latches when the total keyis depressed. A link 911 has a slot and pin connection with said lever227 at its upper end and at its lower end is coupled to a pitman 91lforked to engage either the stud 958 or the stud 958", said pitmanbeing coupled at its rear end to a rocking frame 913 having studs 961and 961 at rearward and forward portions for cooperation with a wipeplate or pawl 821 on a rock arm 818.

The reference numeral 613 designates usual restoring frame or bailcarried by rock shaft 600 and acting to elevate front arms of the levers611.

All of the above designated parts are old and well known and operate inthe familiar manner.

The impression devices comprise pivoted ham ers 715, pivoted hammerdrivers 716 and 716 engaging with the hammers in the usual way, pivotedlatches 717 and 717 it normally restraining said hammer drivers, andlatch displacing pawls 718 connected by springs 780 with the hammerdrivers, said springs serving the double function of impolling thehammer drivers and enforcing engagement of the pawl. 718 with thelatches. Said pawls as usual have tails to cooperate with the camshoulders on the levers 611, so that only when a lever is moved farenough to bring a di it type to printing position can the associatedpawl act to lift its latch.

In carrying out the present invention certain of the hammer drivers andcertain of the latches are specially constructed, such iammer driversand latches eing those de ignated 716 and 717. The regular latches 717have the usual overlapping tails, a, for causing tripping of one latchby another to effect cipher printing in the well known manner. The latch717 farthest to the right is also equipped with one of these overlappingtails, but this particular latch and a number of others to the left areespecially constructed to provide for interruption at one point oranother or at two points at once of the automatic cipher tripping. Tothe upper part of each of the latches 717 (Fig. 10) there is pivotallyconnected the forward end of a pitman B of angular form and widened andbifurcated at its front end to embrace a shaft 13, with provision forforthe the the 1,1ee,cee

ward and backward movement of the pit man accommodating itself to thepivotal movement of the connected latch when lis engaging fron andreengaging with the as sociated hammer driver. There is pivoted to eachof the pitmen B forward of the shaft 13, except the pitman farthest tothe left, an arm B having a laterally turned flange or lip Bconstituting a catch for engaging shoulder B on the adjacent pitman tothe left, such engagement between all the pitmen being normally enforcedby springs B connecting the forward ends of the arms B with suitablefiXQCl support. It will be seen that with such a construction the pitman of the latch 717 farthest to the left, when such latch is displacedeither by its pawl 718 or by the overlapping tail a of the adjacentlatch to the left, will be thrust forward ind its shoulder B will actagainst the flange or lip 13 of the arm B on the next adjacent iitnianto the right, thereby thrust 11g that pitman forward and so displacinghe connected latch, and this operation will continue through the seriesof specially equipped latches so long as the normal condition abovedescribed exists, the pitman of the latch 717" farthest to the right notnecessarily having a shoulder B because the next adjacent latch 717 isnot equipped with any pitman but is tripped in the regular way by anoverlapping tail of said latch 717. Mounted a short distance above theseries of catch arms B and journaled in suitable side-frame supports isa rock shaft which carries a series of cam projections for 'ariouslyoperating upon certain of said arms to displace the same and interruptthe tripping of latches at one or another point or two points at once.in the present instance the construction shown provides for suchinterruption at five different points and the examples of work shown inFigs. 18 to 23 indicate a fifteen bank machine or one capable ofprinting in fifteen decimal places. The particular arrangement of camfingers here shown provides for the so-called splitting singly betweenthe fifth and sixth (Fig. 21) or seventh and ei hth (Fig. 19) decimalplaces and doubly between the third and fourth and sixth and seventhFig. 22), or third and fourth and seventh and eighth (Fig. or third andfourth and ninth and tenth decimal places (Fig. 20), counting from theleft in each instance. The cam fingers on said shaft are thereforelocated to operate upon the catch arms of the fourth, sixth, seventh,eighth and tenth latches, counting from the left and including theregular latches 717. The cam piece C thest to the left comprises threeprojections or fingers c, 0 and 0 (F the fingers c and 0 extendinggenerally at angles of about degrees to each other and the fin gers cand 0 being in diametrical alinefarw ion) and fourth and sixth andseventh late ment. The next cam piece C (Fig. at) is single and extendsat an angle from the shaft intermediate the two fingers o and c of thecam piece C. The third cam piece C (Fig. 5) is likewise single andextends from the shaft at the same angle as the finger c of the firstcam piece C. The fourth cam piece C (Fig. 6) is duplex and of the sameoutline as that portion of the cam piece C embracing the fingers c andc. The finger 0 of this cam piece extends on a different angle from theshaft than any of the fingers of cam pieces already described but thefinger 0 extends on the sam angle as the finger c of the first. campiece C. The remaining cam piece C (Fig. 7), is single and extends fromthe shaft at the sarneangie as the finger c of the first cam piece.

Normallyall of the cam pieces above described are away from thedifferent catch arms P with which they are in alinement. The movement ofthe shaft B to bring the cam pieces into action is divided into fiveperiods corresponding with the manner in which the cam fingers arestepped or spaced apart circumferentially on the shaft. Under thearrangement shown in the present instance the finger of the cam piece Ctakes effect to interrupt the cooperative action between the seventh andeighth latches as represented by the .:-:ample of work shown in Fig. 19.Next the finger c of the cam C and the cam finger C come into play tointerrupt the cooperative action between the third and fourth and ninthand tentl latches, producing the effect illustrated by the example ofwork shown in Fig. 20. Turning of the shaft to the third position bringsthe cam G into action for interrupt ing the cooperative action betweenthe fifth and sixth latches for producing the efiect illustrated in Fig.21. Further turning of the shaft brings into play the finger c of thecam C and the cam finger C for interrupting coiiperative action betweenthe third hes to produce the effect illustrated in Fig. The fifthposition to which the shaft is turned brings intoplay the finger of thcam C and the finger c of the cam C producing the effect illustrated inFig.

The single cam pieces are of the same for mation as fingers of the othercam pieces. each cam finger being tapered 111 form and practicallytruncated, though there is a n r l I m slight convexity of the outeredge. ihlS provides for an easy displacing action of any cam finger uponthe associated catch arm and furthermore for an engagement between thetruncated end of the finger and the upper edge of the catch armcalculated to hold the latter definitely displaced and prevent anyaccidental disturbance of the split adjustment. At the same time theslight convexity of the end of the cam finger provides for an easysliding action when a catch arm has been displaced and the latch withvvhi h it is connected is rocked by the associated pawl 718. (if courseas the shaft is turned *a"rying any cam finger beyond the associatedcatch arm the latter will be restored to normal by its spring B.

The m ans for manipulating the cam shaft com rise a gear wheel B securedto its left and end; a rocking plate D mounted on the left side of theframe work and having a segment B meshing with said gear wheel ll: avertical link B coupled to said plate at its upper end; a rock shaft Bjournaled in s itable hearings in the base of the machine and having acrank arm B coupled to the lower end said link, the latter being givenright angle bend to adapt it for pivotal connection with the twoelements above described, to-wit the plate l) and the rock shaft B whichmove in plan at right angles to each other; an arm B which is secured tothe front end of said. rock shaft where the latter protrudes from themachine casing; and a scale plate B secured to the font of the machine.The arm P is equipped with a suitable handle B by which to move it backand forth and is formed at its outer end as a pointer to register ith.appropriate inscriptions on the p ate B. In the present instance thescale comprises simply a cipher and the numerals 1,. :2, 3, -land 5, asshown in Fig. 12. The plate B is preferably perforated as shown at Z)for receiving a spring pin 7/ of the handle B so as to make certain thepositioning of ti e arm B and the latter is preferably equipped with arollerstud Z2 eigaging an arc-shaped slot in the plate B. it will beobvious that the swinging of said arm B will rotate the shaft B and thedivisions of movement of said shaft efore referred to are properlymeasured by the scale. It will be seen that. this arrangement provioes aready and certain means of locating the split at the point or pointsdesired.

The construction here shown provides a greater nunil of catch arms orcouplers than there are cam pieces for displacing same, there being butfive of the 7 whereas seven couplers are pr vided but it is conside edpurer-able to duplicate the coupler devices at intervening locationswhere cam pieces are not used rather than to resort to the usualoverlapping tails, as better results are secured in the matter of cttiming in operation through the use of these coupler devices andfurthermore it simplifies the proposition of assembling to have thecoupler devices employed throughout the area of the latch organizationin which splits are to be worked. Of course it will be obvious that thearrangement can be indefinitely varied from that here shown,

cam pieces more or less cams being provided and the location of the sameand of corresponding coupler devices changed to suit varying conditions.

As suggested in the opening statement of this specification, it isdesirable with some classes of work to provide for eliminating theprinting of totals of one or more col umns vhere several are beingprinted under a llit adjustment of the machine, and the presentinvention provides for accomplishing this by preventing movement of theimpression hammers which would have to operate in order to print suchtotals. In pointing out parts of the printing mechanism r ference madeto the circumstancethat certain of the hammer drivers were speciallyconstructed, the same being designated by the numeral 716. In thepresent instance the special construction consists in a forwardextension cl, 10, having a straight upper edge. immediately in rear ofthese extensions there is journaled in the side frame pieces a shaft Dcarrying projoctions D D D and D (Figs. 8 and 9) adapted to co-act withsaid extensions for the purpose of obstructing movement of the specialhammer drivers and consequently movement of their hammers. In the construction as here shown there are three of the projections D five of theprojections l) circumferentially spaced from the projection D and threeof them in line with the atter projections; six of the projections Dircumferentially spaced from the projecions D and five of them in linewith the atter; and seven of the projections D cirlumferentially spacedfrom the projection t and six of them in line therewith. The faces ofall of the projections are radial to the shaft D are the straight edgesof the hammer driver QXLGllSlOIlS (Z at normal. The shaft D is mountedto move a limited extent horizontally, in addition to being rotatable,but normally said shaft is pressed to the left by a flat spring Dbearing against its right hand end, see 12, said spring being secured toa suitable part of the frame work. This normal position of the shaft issuch as to bring the projections before de scribed out of alinement withthe hammer driver extensions as shown in Fig. 14, said projections beingspaced apart on the shaft lengthwise thereof. lit will be noted thatextending from the left toward the right hand end of the shaft there arefirst three sets of projections, four in each set, and then two sets ofprojections, three in each set, and then one set of projectionscomprising but two and finally a single projection and that all of thesets or projections are normally out of alinement with the harm merdriver extensions. Furthermore in the normal position of the shaft theradial faces of the rearmost projections D stand vertically, affordingno obstruction to the upward swing of the hammer driver extensions. Itis only when a split or splits are established by moving the handle Bfrom the Zero position that any of the projections come into play. Thelocation and arrangement of the projections must of course correspondwith the location of devices for offecting splits. In the presentinstance the projections are arranged to obstruct three, five, six orseven hammer drivers, beginning with the one farthest to the left. Itwill be noted that where provision is made for e. tablishing a splitbetween the third and fourth decimal places counting from the left thehammer blocking arrangement provides for a corresponding obstruction ofthe three left hand hammers; and further that provision is made for obst'ucting five left hand hammers, which corresponds with the establishmentof a split between the fifth and sixth decimal places. Likewise six orseven hammers can be obstructed to corre spend with the splits which canbe established between the sixth and seventh and seventh and eighthdecimal places. Variation in the number of hammers obstructed is broughtabout through the turning of the shaft D the arrangement of theprojections thereon as heretofore des "r'bee providing for theengagement of the projections i) with the extensions of the three lefthand hammer drivers, while all the remaining hammer drivers areunobstructed by any projections on the shaft. li hen further turned theshaft will present its five pro jections D to five left hand hammers,leaving the others unobs ructed, and so with the six projections D andthe seven projections D The turning of the shaft to desired position isdone when the shaft is in the normal position illustrated in Fig. l-fit,the projections being then out of line with the hammer drivers and sofree to pass between the same when the shaft is turned beyond theposition where the three projections i 3 would be positioned incooperation with the hammer driver extensions. Having been turned to theproper position the shaft will he thrust endwise (to the right) bydepres sion of the total key through connections hereinafter described,so that during an op eration with he total key depressed the se lectedset of projections will perform their function of obstructing a certainnumber of hammers. The turning of the shaft D is done through the sameconnections which turn the shaft B. The rocking plate D hereinbeforementioned is formed with a gear segment D, which meshes with a gearwheel 1) on the left hand end of the shaft D and wide enough (see Fig.12) to remain properly in mesh while the said shaft moves endwise. Theabove construction insures synchronous action of the splitting devicesand the hammer blocking devices.

The means here shown for thrusting the shaft D to the right comprise ajournal head D on the right hand journal of said shaft and a thrust barD slotted to embrace said journal and beveled at its lower end to bearagainst a beveled portion D of the frame-work, see Fig. 12. According tothe construction shown in Fig. 10 the thrust bar is coupled at its upperforward end to an arm 227* secured to the shaft 20st which carries thetotal key bell crank 227. It follows that depression of the total key byswinging said arm rearwardly forces the thrust bar D downward and itslower end outward by reason of the coaction between the bevel thereonand the beveled part D of the frame work. The slotted part of the thrustbar working against the ournal head D forces the shaft to the right,overcoming the spring D and of course the shaft remains to the right aslong as the total key is depressed.

In Fig. 16 a construction is shown which provides for shifting the shaftD to the right or not as desired when the total key is depressed. Herethe upper end of the thrust bar it is formed with an angular slotcomprising a short portion E extending transversely of the bar and alonger portion E running longitudinally of the bar. A stud 1 on thearm227 occupies the slot and with the forward end of the thrust barelevated as shown in Fig. 16 it will be obvious that the rearward swingof the arm 227 resulting from depression of the tota key will have noeffect upon the thrust bar. A spring E connects the thrust bar with saidarm, thus normally holding said bar in such relation to the arm as notto be affected thereby. The bar extends forward of the slotted portionas shown at E the extension having cam formation on its upper edge whichis engaged by a roller stud E carried by one arm E of a bell cranklever. The latter is pivoted on a cross rod of the machine below thekeyboard and its other arm E carries a roller stud E bearing against aslide bar or strip F suitably mounted under the lower keyboard plate212. A pin F secured to the forward part of this strip or bar projectsup through slots in the keyboard plates and through a slot in an indexplate F Fig. 17, secured on the upper keyboard plate. Said pin issurmounted by a knob F which has a pointer F to register with suitableinscriptions on said plate. The strip or bar F is formed with a cam risefnormally standing just forward of the roller stud E and normally theknob F is at'the forward end of the slot in the index plate F thepointer F registering with the proper inscription, such for example asthe word Print. By pushing the knob back and bringing said pointer toregister with the other inscription, e. g. the words Not print the camrise 7 of the strip or illustrate various kindsof work, of which amachine equipped with the present invention is capable. Fig. 18represents work of the machine at normal, when any amount up to thedecimal capacity of the machine can be set up on the keyboard,registered in the accumulator and printed and a total struck extendingthroughout the decimal arrangement of the parts. Fig. 19 illustrateswork when a single split is established for the running of two separatelists and the striking of a total of each. In this case the handle B ismoved to the first position, establishing the split between the seventhand eighth decimal places as before described and the movement isinsuflicient to bring any of the projections on the hammer blockingdevice D into effective position. There fore as none of the hammers willbe obstructed upon depression of the total key and operation of themachine a total will be struck for each list. Fig. 20 illustrates workin which three separate columns are printed and no total of the lefthand column, though totals of the other two are printed. This work isdone with the handle B at the second position when the splits areestablished between the third and fourth and ninth and tenth latches.When so adjusted the handle has turned the shaft D so as to bring theprojections D thereof to such positions that when said shaft is movedsidewise by depression of the total key these projections will comedirectly over the extensions (Z of the three left hand hammer driversand consequently the connected hammers cannot operate and no total willbe printed under the left hand column. Fig. 21 illustrates an example ofwork in which a split is estab lished between the fifth and sixthdecimal places, which is brought about by moving the handle 13 to thethird position. This results in further turning of the shaft D bringingthe five projections D thereof to such positions that when the total keyis depressed these projections will move directly over the extension (Zof the five left hand hammer drivers. Consequently in a totalingoperation no total will be struck under the left hand column. When thehandle B is moved to the fourth position for establishing splits betweenthe third and fourth and sixth and seventh decimal places (Fig. 22) thefurther turning of the shaft D brings the six projections D thereof tosuch positions that when the shaft is moved sidewise in depression ofthe total key these projections will move directly over the extensions(Z of six left hand hammer drivers and consequently no totals will beprinted under the two left hand columns. ll iovement of the handle B tothe fifth position establishing splits between the third and fourth andseventh and eighth decimal places (Fig. 23) causes the shaft D to bringits seven projections D to such positions that when the shaft is shiftedthrough depression of the total hey these projections will move directlyover the extensions (Z of seven left hand hammer drivers, witii theresult that no totals will be printed under the two left hand columns.Of course it will be understood that with a construction such as thatshown in Fig. 16, unless the knob F is pushed back to the Not printposition shown in Fig. 17, there will be no blocking of hammers andtotals would be printed under all of the columns.

To prevent accidental movement of the knob, the connected strip F isformed with a V-shaped portion f engaged by a roller stud f on the upperend of a bar F which is slidingly mounted on the frame-work of themachine and upheld by a spring This construction also insures fullmovement of the strip by reason of the camming action between the parts.
